J. David Archibald

from Wikipedia, the free encyclopedia

James David Archibald , called David, (born March 23, 1950 in Lawrence , Kansas ) is an American zoologist and vertebrate paleontologist who specializes in fossil and modern mammals . He is also known for his research on mass extinction at the Cretaceous-Tertiary boundary .

Archibald graduated from Kent State University with a bachelor's degree in 1972 and received his PhD in paleontology from the University of California, Berkeley in 1977 . As a post-graduate student , he was a Gibbs Instructor at Yale University . From 1979 he was Assistant Professor and later Associate Professor at Yale and curator of mammals at the Peabody Museum of Natural History . In 1983 he became a professor at San Diego State University and curator of mammals at the museum there.

He investigated the change of fauna, particularly of mammals, at the time of mass extinction on the Cretaceous-Tertiary border. He advocates a gradual extinction, mainly caused by terrestrial influences (receding seas, especially the Western Interior Seaway , volcanism, habitat fragmentation), with the additional influence of asteroid impact. He found that even before the impact, the number of dinosaur species in North America had decreased by 40%.

From 1994 to 2006 he was a participant in international expeditions (Urbac) to research the fossil fauna of the late Cretaceous (age 90 million years) on the shores of an inland sea in Uzbekistan . He examined the mammalian fauna (which was dominated by higher mammals) and fauna change.
